* useful for timers or other such counting effects
*
* e.g
* countingMap.put(object); // puts (object, 0) into the map
* countingMap.increment(object) // adds 1 to the value of the object (object, 1)
* countingMap.decrement(object) // decreases the value at the object's key reference by 1 (object, 0)
